Abstract
Embodiments of a polyethylene composition are provided, which may include a first polyethylene fraction comprising at least one peak in a temperature range of from 40C to 75C in an elution profile via improved comonomer composition distribution (iCCD) analysis method, where a first polyethylene area fraction is an area in the elution profile from 40C to 75C, and where the first polyethylene fraction area comprises from 45% to 65% of the total area of the elution profile; and a second polyethylene fraction comprising at least one peak in a temperature range of from 85C to 110C in the elution profile, where a second polyethylene area fraction is an area in the elution profile from 85C to 110C, and where the second polyethylene fraction area comprises from 15% to 35% of the total area of the elution profile, wherein the polyethylene composition has a density of 0.905 g/cm3 to 0.918 g/cm3, a melt index (I<sub>2</sub>) of 0.7 g/10 minutes to 3.5 g/10 minutes, and wherein the composition has a melt index ratio ( I<sub>10</sub>/I<sub>2</sub>) that meets the following equation: I<sub>10</sub>/I<sub>2</sub> < 7.0 - 1.2 log (I<sub>2</sub>).
